*COMPUTING-CARD-STAFIPING MACHINE.

Patented Feb; 7, 1922 Application filedJ'uly 7, 1919. Serial No.309,189.

To all whom it may concern:

Be it known that I, GEO GE WVILLIAM OonLL, a subject of the King ofGreat Britain, and residing at 298 St. James.

Street, in the city and district of Montreal, in the Province of Quebec,in the Dominion of Canada, have invented a new and useful Computing-Card Sta mping Machine, of which the following is the specification.

The invention relates to a time card stamp as described in the presentspecification and illustrated I in the accompanying drawings that formpart of the same.

The invention consists essentially of the novel construction andarrangement of parts, whereby the action of the stamp in relation to thecard is governed by the operation of the mechanism actuatedsynchronically with i electrical means effect the shaping of the cardautomatically in synchronism with. a

clock or other timepiece; to facilitate the handling of small and largebodies of workmen, particularly in regard to their wage earnings; toreduce the clerical work re-.

quired in computing wagesand costs and consequently economize greatly inthe matter of overhead charges; and, generally to provide an efiicient,durable and serviceable machine for preparing a card fora calculatingmachine.

Figure 16' is a detail of a card following shown as formed inrectangular shape, having a longitudinal opening 2 terminating adjacentto the rear end of the table and a belt hole 3 near the front end.

The table lis supported on the four corner posts a and the intermediatestandards 5, which are screwedto the table and to the base 6, the latterbeing in the form of-a' plate.

This completes the frame of the machine and it is on this frame that allthe brackets and operating parts are supported with the exception of thetimepiece, which forms no The longitudinal guide bars 13, Figs. 2,

3 a'nd4 arein angle form, each having a vertical section 14 secured tothe table 1 by "screwsan intermediate section 15, and a horizontalsection 16 extending inwardly towards the edge of the opening 2. 'Theguide bars 13 also have an interiorcut away portion 17 which has wallsprojecting upwardly and to the inside to form a bearing forithel'stop.

form tracks at each side ofthe opening 2 and The guide bars 13 with thetable surface:

in and on these tracks thesliding stop 18 i is introduced, the stopbeing inlplate' form and having the downwardly projecting flanges 19fromitslongitudinal edges .and the outwardlyprojecting flanges 20 fromthe ,lower end of the flanges 19, theflanges 19 engaging the innersurfaces ofthe vertical sections 17 and thefianges 20'sliding on thetable top under the horizontal sections 16.'

The toothedrack 21 is secured to the underside of the stop 18 in thecentre thereof 7 by the screws 22 and extends the fulllength of'thestop.

The driving gear wheel 23 coacts the rack 21 andis mounted on the shaft24 f =journalled in the hangers'25, and is formed with the segmentaltoothed portions 26 and i V 27 separated by the smooth rim portions 28and-29, this gear being-actuatedby a spring 'in the casing 30.

The gear wheel 31 is engaged bythe spring i pawl 32 rigidly secured tothe driving gear 23. f I g r V The escapement mechanism is formed withthe gear wheel 33 fixed inoperative relation to the driving gear wheel23 and .coacting and heldlby the pinion 34 mounted on the shaft35journalled inthe hanger 36, theshaft 35' also carrying? the escapementwheel 37,

rigid withthe hanger 36.

the spring and only held still by the escapement in an arrangementsimilar to many clock mechanisms.-

L 'The solenoid- 44 is electricallyconnected to theclock 45, so thatevery five minutes or any other period of time, the solenoid 44 isenergized,which has the effect of picking up the escapement rod 39'toj'bring in the periodical operation of the escapement mechanism. r rr By thisarrangement, the card stop 18 is operated along the table lonits tracks, being moved towards the rear end of the table a set distanceevery five minutes. As soon as the segmental portionv 26 of the-gear 23has 1 finished its operation of taking the stop 18 to the rear endof thetable 1, then the smooth rim portion 28 is turned under the rack and asthere are no teeth to holdthe stop 18,

the latter is quickly returned to the tray 7 to commence its operationsonce more in travelling to the'rear end of the table, this timebeingpropelled by the segment 27, until the smooth rim portion 29 isreached,when f f the same return action occurs. 7

The spring 46 contained in the frame 47 is wound on the spindle 48,which also carriesthedrum-49. V r

The cable 50 windson the drum 49 and extends'through the table and'underthe tray 7 to the stop 18, where'it issecure'd. Q Immediately thatthesegmental gear teeth release the rack there is nothing to hold the stop18 from being pulled by the spring 46, con-1 i sequently it very quicklyreplaces the stop .in its starting position atthe end of thepredetermined period of 7 time over which the machine operates.

The knives 51 and 52'are each formed with theback 53 to which the blade54fis secured,

the latter having an outturned extremity 55 'i to; finish the clippingfrom the card and form the shoulderirequired. The blades 54engage" withthe sides of the guides 16 (Figs. 4 and 1 -18) in a scissor-like actionto cut the card.

The backs 53 are pivotally secured in the i bracket 56 rigidly securedto the table 1 by the screws 57 and braced by the tie bolts 58..

The front ends of the kniie backs 54are pivotallysecured to the solenoidcores 59 and 60 of the solenoid windings 61' and 62. The solenoids 61and '62 are supported in the framei63, which-is mounted on the frame 7'64 securedto the table 1. V

The upper ends of the'cores 59 and 60 are suspended bythe springs 65 and66 from the hooks 67. and 68 secured to the upper end of the frame 63.

The solenoids 61 and'62 areinclu'ded in a 1 plan ofelectric wiring morespecifically set forth hereinafter .in a description of the electricfeatures. It is sufficient to say here that the spring electrical switchcontacts 69 and 70" are supported from the switchboard mechanism securedto the front'of the 7 stop 18 and on being pressed inwardly toward thestop close circuits in coaction the switch contacts 71 and '72.

The Card 73 to be clipped' is itselfthe ini struinent for operating thecontacts 69 and 70, engaging them edge on as it is thrust in toward thestop (Fig. 8). V

.70 and core,86. I

The card73 in its uncut state first operatesby theothercontact,conseonently only one knife will operate as only onesolenoidw'ill be energizer. and asthe drawing in o'l 'said core againstthe spring pull pushes the knife downwardly the card will be clipped onone side'only. The-spring pullsthe lrniile upwvardly onthede-energization ofthe sole noid and places the machine in readinessfor the second operation. the insertion of the cardthe card engages anelectrical contact, but only one as the card has been already clippedthereby providing clearance between the card and the other contact,theretore'the card operates the knife on theunclipped side and as thestop has since travelled aconsiderable distance, if the elapsed time isa good part oi a' day, the clipping this time is much d eper into thecarn'with the result that two shoulders 74 and '?5 are formed and it isthe distance between these shoulders'along a longitudinal line throughthe card that measures the time between the firstand second operations.

The following; is;a brief description of the electrical operation inFigure 6 one plan. of wiring suitable for the operation oi": the knivesis shown and in this figure 69 and T0 are the spring switch contactsand71 and 72 are the relatively rigid'contac-ts, all carried by the stop asexplained. r From the contacts 69 and Tithe Ina-in leit hand circuitextends and from the contacts 72 the main right hand circuit oi;- tendshV The plan of operation is, as a hiresaid, to first cut out one circuit,while the other is operating, thus the left hand circuit will he cutout. automatically and the ri'sh hand circuit 'energizd. I There areseveral ways or doing this to any one versed in the art or electricity,hut herein a comparatively simple arrangement is shown. r i

At the right hand the solenoid T6 is connected-through its core I? toj-f-he contacts and 72 and from thecore'an 8'e:-:tends to a switchcontact 80, which coacts with switch. contact '79 and when thecoreli?is, drawn in. the arm T8 closes the switch contacts 7 9 and S0ands'inultaneously d aws the contacts 79 and 72 tothe left and out fromunder the path of the knife that is to do the cutting arin S etc (Figs.6 and 8.) s in auxiliary e 1110??(1. to

' The uncut card'naturally operates both contacts 69 and 70,consequently this cut out plan o'l'-wii*i11g is essential, where thecontacts are arranged as shown or substantially so.

The switch contacts may be held open if desired by means of a hook 9%which normally lies over the top of the card and which upon the movementor" arm 81 to the left is adapted to'hook over side of the card andprevent the return of arm Sl to the right until the card isremovedrlroni the machine.

Such an arrangement not essential since other means are provided "forrestoring arm 81 to the left and re closin 'contacts 83S-fl. If the hookconstruction is employed the car 81 should preferably have a los" nationspring connection with part '78 to pc niit this part to return upon thede-energizationor solenoid 76 and thereby break the circuit throughcontacts 79 and 80. This hook arrangement is not absolutely essentialbut provides an additional interlock which in certain cases mayhedesirable.

The switch electro-rnagnet 95 isconneoted to line wire 90 and contact99. conseque y on the closing of contacts '79 and 89 the ct rent flowsfrom line 91 through contacts T9-8l a d'haek through electroe '95 toline 90 In this way the GlQCL-if' magnet is en are 96 forming; a switchnieinher connects electrically i cts 97 and 98, which brings li .enoidinto the energized electric circuit. the solenoid 6:2 heing' alsoconnected to the e wire 91. The core 60. which isspring-l n i:w to itsper po sition, is drawn in the wii 1 in the usual manner and actuatesthe with the result that thecard is side.

It is desirable in o'rde to avoid coincident operation of the lGl'lYQSto establish an indie pendent branch connection from the switch clippedon that contact 99 leadingto the linewire 90; The

switch contact 99 isbroughtinto engagement 7 with the switch contact100,,bth mounted on -thetray 7, by'the insertion of the card under thelniife opens them by an extension from roller 99 (Fig: 10). The contact100 is per manently connected withthe switch contact 101' and the lattercoactswith the switch contact 102 electrically connected 'Wlbllfhfisolenoid 62. The switch contacts 103 and 10a are'in the main right handoperatingcircuit and are normally closedfbut the descent of the core 60contacting with contact 103' (see Fig. 6). In consequence the solenoid76, the switch electro magnet- 95, the switch electromagnet87, theswitch contacts 70 and'72, and I the switch contacts 7 9 and 80-arecutout and the connection of the switch contacts83and 8e readjusted, butbreaking of the main operatlng circultestablishes a new connection,

for the 'switch contaets101-and 102 are brought together vbythe descentof core 60 and as contacts 99' and 100 have been connected by the card,there is an uninterrupted connection between the two line wires '90 and91- including the'knife operating solenoid 62,

' therefore the core 60 is still magnetically held by the coil, therebykeeping the knife to its lower position, untilthe cardis withdrawn and"avoiding any possibility 40f a double operation. L The next operationconcerning the card is the cutting outof the other side and this as V arule does not occur for some hours afterwards, consequentlythe stop hastravelled 0 some distance: which proniises a much deeper cut in thecard. e V r The card is inserted andas the right hand .side is cut awayto the shoulder 74, there is nothing to engage the contact 70, which isthus leftundisturbed. c V

i The contact 69Yis howeverengaged by the uncut cardon the other sideand is brought into engagement with the contact:71 and this energizesthe solenoid 85 and by this means thecontacts 69 and 71 are withdrawnfrom the path of the knife 51, being connected to the core 86. The arm105 is also connected with the core 86 and through its oifset 106engages the switch contact 92-and brings it into engagement withthesw'itch contact 93, which is 91. p g I i c It has already beenexplained that by re- 7 adjustment of'rthe right hand circuit to itsnormally open state, the switch oontacts83 and 8 1 have been reconnectedand in consequence there is now an electrical connection establ shed,which includes the switch electro-magnet 109, that operates the switchcontact 110 into engagement with the switch contact 111. i The closingof the switch con tacts 110 and 111 is followed almost instantaneouslyby the connection of the switch contacts 112 and'113 by the varmature11d,

directly connected to the line wire being a switch 7 member operated bythe:

switch electro-magnet'1'15 and then the solenoid6l is energized whichbrings down the coref59 against the upward spring pressure andconsequently the knife 51 a V "The descent of the knife opens the switchindicated diagrammatically by the switch contacts 116, and 117 in thesame manner as 7 described for the righthand part of the system, and-bythis means the main operatoperated switch contacts 118 and 1191 and ingcircuit isbroken and thesolenoid 61 kept v energized to' hold the knifedown and prevent double operation by the branch connection to thelin'ewire through the card the switch contacts 120 and 121 closed by thedescent of the knife 51. r

' T he removal of thecard re-establishes all] these contacts to theiroriginal positions and it will be found that the card has a deeper cuton the opposite side forming the shoulder 74 and completing the card'asan instrument of operating another machine and receiving therecord, V itIn the operation of-the-escapement mech- The {contacts and 128 areconnected to the power represented by the line wires 124: and 125through theresistance126, which is constructed to magnetize the armature127 forming a switch operating member. The

line wire 1125 is connected through to the V solenoid't l and the linewire 124is connected to the solenoid 14 through the switch contacts 128and 129, the contact 129 being brought into engagement with the contact128 by the armature 127. The core 43 is 1 thus operated, which swingsthe escapement,

rod and releases the escapement wheel and thereby puts the driving gearinto active en gagement with the rack and stop'to the extent of one 'pintooth ofthe escapement wheel. Briefly the operation of the machineisasfollows The card in its original state as handed to. a workman isinserted by the man into the inachine alongthe tray and under the, timeswitches, that hold the operating knives down pending the removal of thecard;

The man pushes in the card until it reaches the stop and consequentlythe electrical spring contacts and'these are moved in to make theelectrical connections and the cut is made, which removes the-piece fromthe card. p 1

The worlcrnan'proceeds to his duties and on the completion of a job oratfthe finish of the day or part day, he again takes: the

The detailsof operation have been fully described hereinbefore,-so allthat is necessary to say in addition is that a considerable variationmay be made in the manufacture of this machine, without departing fromthe spirit of the'invention, and solong'as such changes are Within thescope of the claims for novelty, the protection accorded shall not beinvalidated.
